How to Make a <td> Clickable As a Link (Without Javascript)

Question

I am writing some code for sending HTML e-mails. Due to the non-standard nature of e-mail clients, I am restricted to some pretty antediluvian code (no Javascript, no divs, no CSS shortcuts, etc.)

The call-to-action buttons are TDs but so far I haven't been able to make the whole button clickable; just the text in the middle.

The code is something like

<table width="100%" border="0" cellpadding="0" cellspacing="20">
            <tr>
            <td align="center" valign="middle" width="33%" style="background-color:#6483c1; border:1px solid #44619a; border-radius:2px; padding-top:20px; padding-right:10px; padding-bottom:20px; padding-left:10px;">
            <a href="http://littlehotels.co.uk/travelinsurance.php" target="_blank" style="color:#FFFFFF; text-decoration:none;"><font size="3" face="Arial, Helvetica, sans-serif" color="#ffffff"><b>Travel Insurance</b></font></a>
            </td>

I have already tried adding display:block to the td style, but that didn't work.

Am I trying to do the impossible?

Answer 1

Make the anchor a block level element and move the padding from the table cell to the anchor:

<table width="100%" border="0" cellpadding="0" cellspacing="20">
  <tr>
    <td align="center" valign="middle" width="33%" style="background-color:#6483c1; border:1px solid #44619a; border-radius:2px;">
      <a href="http://littlehotels.co.uk/travelinsurance.php" target="_blank" style="padding:20px 10px;display:block;color:#FFFFFF; text-decoration:none;"><font size="3" face="Arial, Helvetica, sans-serif" color="#ffffff"><b>Travel Insurance</b></font></a>
    </td>
  </tr>
</table>

Answer 2

You cannot make a <td> clickable without JS
Enlarge the inner <a> size instead - to cover the needed area,
setting it's display to block might help.
